ROLLIN L. DRAKE, OF POE-T ARTHUR, TEXAS, ASSIGNOB TO THE TEXAS OF NEW YORK, N. Y., A CQRPQR-ATION OF TEXAS.

CAN-MIAXING IVIACHINE.

Application filed November 30, 1920.

To all whom it may concern Be it known that 1, Roman L. DRAKE, a citizen of the United States, residing in Port Arthur, in the county of Jefferson anl State of Texas, have invented certain new and use ful Improvements in Can-Making Machines, of which the following is a specification.

This invention relates to mechanism for the manufacture of cans and containers from metal ware and has special reference to the provision of apparatus adapted tobe used in the construction of a member having a rim or flange portion attached to another metal part.

The accompanying drawings illustrate a preferred form of the invention and reference will now be had to the same in order to give a detailed description of the invention.

Figure 1 is a side elevation of an apparatus constructed in accordance with the invention and constituting an embodiment thereof.

Figure 2 is a front elevation partly in section.

Figure 3 is a plan view of the apparatus.

Figure 4 is a section drawn to a larger scale than the other. drawings and showing in detail the solder melting appliance and 30 certain parts which may be soldered together in the operation of the machine.

Figure 5 is an elevation partly in section of a type of can adapted to be constructed in the practice of my invention.

The apparatus includes a frame or support 10 upon which is mounted the shaft 11 which may be driven by the pulley 12. A shaft 13 which may be journaled in sleeve bearings 14 and 15 is driven by the shaft 11 through the bevel gears 16, and is attached to a stem 17 which is fastened to a heating jacket 18. Heat is applied by means of the burner 19. At the base of the heating jacket is a plate 20 which is composed of soft steel or other similar material and has an annular soldering rim 21. As the bearing 15 is subjected to considerable heat it may well be provided with a grease cup 11 adapted to feed a solid grease to the bearing through the pipe 39. A heat retaining hood 40 may be disposed over the heating jacket 18, if desired.

Beneath the heating jacket is a disc or wheel turn-table 22 containing a number of openings 23 arranged in annular forma- Serial No. 427,299.

tion adjacent the edge of the table, as clearly shown in Figure 3. The table is .rotatively mounted upon a suitable support 24:. The arrangement is such that upon a rotation of the table 22 the several openings :13 may in succession be brought immediately underneath the soldering rim 21 of thc heating jacket 18. To the underside of the table in proximity to each of the openings 23, a number of brackets or supports 25 are attached. Each support carries a spring 26 which controls a hook or gripping member 27. The upper portion of each hook member is provided with a crook or projection which is adapted to engage a thread or rim of the can member which is being soldered. Upon a rotation of the table 22 the lower end of the hook member is adapted to travel along a track 28 having a cam or raised portion 29, the cam being arranged to push the hook upward against the resiliency of the spring 26.

, A foot lever 30 is connected by means of a link 31 to a lever 32 which is pivoted at 33. The lever 32 terminates in a yoke 34: which is loosely mounted in a circumferential groove in a collar 35 located on the shaft 13. The lever 30 may be provided with the tension spring 36. Upon depressing the foot lever the shaft 13 carrying the heating jacket 18 is raised and upon releasing the foot lever the heating jacket is brought into close proximity to the table 22. In operation one of the members to he soldered, such as the annular member 38 is placed adjacent one of the openings 23 and the other member 87 is dropped through one of the openings 23. The member 37 is hollow and has a rim or flange by which it hangs upon the member 38. The parts to be soldered are introduced in one of the openings above the cam 29 of the track 28 at which points the hook extends upwardly out of engagement with the can member. Upon revolving the table 22, however, the igripping member rides ofi the cam 29 and engages the flange of the member 37 as is clearly shown in Figure 4. By reason of the spring 26 the gripping member 27 exerts a pull on the member 37 thus holding it down tightly upon the rim member 38 during the soldering operation. By rotating the disc 22 the parts to be soldered are brought immediately beneath the heating jacket 18 and the jacket is lowered so that COMPANY,

the annular soldering rini 521 of plate 20 comes in intimate contact with the parts to be soldered. The plate 20 having been brought to a snfiicient temperature to cause solder to flow the operator then applies the solder to the rotating rim which quickly applies the melted solder along the seam between parts 37 and 38 and these parts are readily sealed together.

It sometimes happens that after the operator has placed the parts to be soldered on the disc 22 and the hook 27 has gripped the member 37, that some adjustment of the parts 37 and 38 may be necessary. For this reason the release bar 41 is provided. This bar extends through an opening in the track 28 and is adapted to engage the lower end of a hook 27. The bar is operated by a foot lever 42 which is pivoted at 43. \Vhen it is necessary to adjust the members 37 and 38 the operator depresses the toot lever 42 thus moving the release bar upward so that it engages one of the hooks 27 and pushes it upward thus releasing the hook from its engagement with the member 37 and permitting the parts to be manually moved into a correct position in relation. to each other. The operator then releases the foot lever and the hook 27 is allowed to grip the member 37 and thus hold the parts in position for soldering.

A structure of preferred form and construction has been illustrated and described for the purpose or showing a. way in which this invention may be used, but the inventive thought upon which this application is based, is broader than the illustrative embodiments thereof, and I therefore intend no limitations other than those imposed by the appended claims.

What I claim is:

1. A can soldering machine comprising a rotatable table, openings therein throu h which the members to be soldered may be hung, a rotatable solder melting member adapted to be brought into contact with the members to be soldered, and gripping members underneath said openings and adapted to engage with members to be soldered, extended through the openings, so as to exert a downward pull on said members.

2. A can soldering machine comprising a rotatable support for the members to be soldered, a rotatable solder-melting member and means for raising and lowering the same, a spring-controlled hook fastened to the rotatable support, and a cam track over which the hook travels.

3. A can soldering machine comprising a rotatable support having openings therein,

a hook adjacent each opening and fastened to said support, a tension spring controlling each hook, a track along which the several hooks are adapted to travel during the rotation of said support, and a cam in said track whereby the several books may be moved in an upward direction against the resiliency of the spring while passing over said cam.

4.. 'A can soldering machine comprising a turntable, openings therein through which members to be soldered may be hung, a solder melting member adapted to be brought into contact with members to be soldered, spring operated means adapted to grip members extending through said open ings so as to exert a downward pull on same, and an actuating cam adapted to release said spring operated means from en gagement with said members at a predetermined time.

5. A can soldering machine comprising a turntable, openings therein through which members to be soldered may be hung,,a solder melting member adapted to be brought into contact with members to be soldered, hooks adapted to engage a member extended through said openings, and resilient means for exerting a downward pull on the hooks.

6. A can soldering machine comprising a turntable, openings therein through which members to be soldered may be hung, a solder melting member adapted to be brought into contact with members to be soldered,

a bracket attached to the turntable adjacent each opening, a gripping member mounted on each bracket and adapted to engage a member extended through said opening, resilient means adapted to exert a downward pull on said gripping member, and a cam over which the gripping member is adapted to travel and arranged to move the gripping member upward at a predetermined point in its travel.

7. A can soldering machine comprising a rotatable table, openings therein through which members to be soldered may be hung, a solder melting member adapted to be brought into contact severally with members to be soldered, hooks adapted to engage members extended through said openings, resilient means for exerting a downward pull on said hooks, and a circular cam track adapted to be engaged by the hooks and having an elevated portion capable of forcing the hooks in an upward direction.

In witness whereof I have hereunto set my hand this 22d day of November, 1920.
